#2639: CarpetLib internal error with PreSync and analysis thorns
Reporter:Samuel Cupp
Status:new
Milestone:
Version:development version
Type:bug
Priority:major
Component:Carpet

I’ve found a strange error involving variables from analysis thorns with multiple timelevels (such as WeylScal4 and ML_ADMConstraints). The error is

WARNING level 0 from host r1i6n25.ib0.sawtooth.inl.gov process 0
  in thorn CarpetLib, file /home/cuppsamu/toolkit/Cactus/arrangements/Carpet/CarpetLib/src/gdata.cc:315:

This error comes from repos/carpet/CarpetLib/src/gdata.cc:

void gdata::find_source_timelevel(vector<CCTK_REAL> const &times,
                                  CCTK_REAL const time, int const order_time,
                                  operator_type const op, int &timelevel0,
